Cross Domain - CORS

Doesn't Work document.getElementsByClassName('myiframe')[0].contentWindow.document Uncaught SecurityError: Failed to read a named property 'document' from 'Window': Blocked a frame with origin "https://xxxxxxxx.com" from accessing a cross-origin frame.

I've had the extension for years without any incident until May 28, 2024. When this extension is turned on it's broken the account login page for: The Globe and Mail, Twitter, The Athletic, The Atlantic, American Express, The New York Times and has made it so videos on YouTube never load. This is extension is effectively broken now

Version 0.3.0 updated on 28-May-24 is broken. I have used the extension for many years with the default wildcard rule deleted and only a single local IP address rule but as of today's version many sites such as youtube do not now work at all when the extension is loaded. Edit 01-Jun-24: New version 0.3.2 fixes Youtube but other sites (e.g. Feedly) are still broken. I have been using another CORS extension which works fine everywhere.

interferes with Instagram when enabled

Regex doesn't work. It doesn't accept for example: ^(http:\/\/)(localhost:3006)(.*)$. Anything with "\" cannot be added. Also, some simple regex such as ^(.*localhost:3006.*)$ doesn't work. Even something like this won't match ^(.*l{1}o{1}.*)$ or ^(.*lo.*)$

Doesn't work. Will only ever show a red X instead of a green +.

Useless

Lacks documentation and examples. When it doesn't work you have no way of knowing why. There's no easy way to tell if your URL patterns configured are working. It's not clear what types of CORS it's allowing or denying. It's not clear if regex in URL patterns works or what regex will work and what won't.

This extension blocks my ability to use Google Maps satellite view. I have removed the extension tested, reinstalled the extension and tested again. This extension is the only variable to Google Maps not working. May not be an issue for you, just wanted to let others know if you're experiencing issues.

Conflict with google drive.

This extension causes server errors when working in Google Drive or Google Docs.

It sometimes breaks the entire connection making it pointless. Literally can't load any pages with Chrome when this is enabled (for a single site nonetheless)

It works fine unless I use slash characters to specify URLs. I sent feedback on the website and am looking forward to bugfix.
